8.2.7 Input Terminal Mounting Plate Assy Option
The frequency converter has component options that can be mounted on the input mounting plate. This results in differing unit configurations. These options
include input terminal blocks, input disconnect, RFI filter, input fuses, and an additional cooling fan. These options may need to be removed from the mounting
plate assembly to reduce the weight of the assembly for ease of removal.
1.
Disconnect the input power wiring from terminals L1, L2, L3, and earth connector.
2.
Remove the upper most bus bar retaining nut (17 mm) from each of three terminals.
3.
If a disconnect (not shown) is mounted, remove the disconnect from the terminal plate assembly to reduce the weight of the terminal plate as follows.
3a
Loosen the connection nut (17 mm) between the fuse and disconnect.
3b
Remove the 4 mounting screws (T40) from the disconnect.
3c
Note that the weight of the disconnect can be up to 16 kg (35 lbs). Slide disconnect down to clear fuses and remove.
4.
If a cooling fan is mounted, disconnect the fan cable.
5.
If an RFI filter is mounted, disconnect the RFI cable.
6.
Note that the weight of the terminal plate without the disconnect can be up to 20 kg (44 lbs). To remove the terminal plate, remove the 8 retaining nuts
(10 mm) from the terminal plate and lift the entire assembly from the mounting studs.
Reinstall in reverse order of this procedure. Tighten the 10 mm mounting nuts to 4 Nm (35 in-lbs), 17 mm connection nuts to 19 Nm (170 in-lbs) and T40 mounting
screws to 9.5 Nm (85 in-lbs).
